PI 4 - second HDMI out for audio.

    Hi


    So two years or so ago, I asked this question here:

    RE: LibreELEC (Leia) 9.2 ALPHA1 with Raspberry Pi 4B Support

    Hi All, new here...

    Anyway - the new Raspi has potential to solve one of my problems. My TV has one 4K HDMI input, but my reciever is 1080P only. Unfortunatly the TV will only send stereo back down the ARC if the source is external. So I need a way of getting passthrough audio to the reciever.

    Will it be possible to use the second HDMI to output the audio (with or without 1080P or lower video) while sending the full 4K video to the TV on the other HDMI?

    If so, that would be great. Thanks for any…

    The answer indicated technical feasibility - but low priority and unlikely to be implemented any time soon.

    Now we have full release 10 for the Pi 4, I was wondering if "anytime soon" had happened over the last two years, or if not, is there still a chance. Or is it just unlikely to happen at all?

    Thanks.
